fix(core): commands shouldn't hang when passing --help (#34506)

## Current Behavior
`--help` on commands that hit yargs help are hanging

## Expected Behavior
It doesn't hang. This contains a quick fix in adding the process.exit
call, but also adds the unref needed to maintain previous working
behavior. We'll need to investigate long term if additional areas keep
commands alive, but adding this unref theoretically allows removing the
process.exit calls from `nx show`
